This work aims to develop a cost-efficient, rapid-response, resilient, and robust action plan that reduces operational inefficiencies across multiple possible future manufacturing scenarios. The proposed approach introduces a novel integration of Reconfigurable Manufacturing Systems (RMS) with the Manufacturing-as-a-Service (MaaS) paradigm, enabling dynamic sharing and allocation of reconfigurable machines, tools, and resources across diverse production contexts. This shift from dedicated, fixed-capacity assets toward flexible, on-demand manufacturing capabilities enhances system adaptability and responsiveness under uncertainty. To support decision-making at different planning horizons, a two-stage framework is developed that jointly addresses strategic RMS design and tactical rebalancing actions triggered by disruptions and disturbances. The resulting methodology provides a robust, data-driven basis for improving resilience, resource utilization, and operational continuity in volatile aerospace fuselage manufacturing environments.
